Is that the reason? I would think --'a' would be z, but that is my own
internal logic :)
But, why is --'a' (or any a-zA-Z) -1? Why doesn't, at least, it evaluate
'a' to true (1) and --'a' = 0 (or undef, since I don't know why it
should return a true value)? I guess there must be a reason, but it
isn't documented from what I can see.
Cheers,
Kevin
